Definitions

the present invention relates to a stencil printing machine in which a stencil sheet wound on a stencil drum is pressed against a opposite which is located close to the stencil sheet, like a press of the internal pressing type, in order to perform stencil printing process.
FIG. 1 is a schematic diagram representatively showing one example of the stencil printing machines of the prior art internal pressing type
the prior art stencil printing machine is composed of a printing mechanism 4 having a stencil drum 16 and a opposite 17 which are located with their external peripheral surfaces being close to each other inside of a machine body 50, a paper feed mechanism 5 serving to feed paper 22 as placed on a paper feed tray 23 to the printing mechanism 4, and a sheet discharge mechanism 6 serving to the printed paper 22 to a sheet discharge tray 34.
the stencil drum 16 as described above is provided with a stencil sheet wound on the external peripheral surface thereof.
the stencil drum 16 is designed to be detachable from the machine body 50 in order that another stencil drum can substitute therefor in accordance with a desired color and so forth and that the stencil drum as detached can be used in another stencil printing machine.
the stencil drum 16 is provided with an internal pressing roller 47 therein for outwardly pressing the internal peripheral surface of the stencil drum 16.
the internal press roller 47 is linked with a printing press motor 48 through a spring 49 in order that the driving power of the printing press motor 48 is transmitted to the internal press roller 47 through the pressing force of the spring 49 to control the pressing force of the internal press roller 47 toward the internal peripheral surface of the stencil drum 16.
the printing press motor 48 is driven by making use of a directive pulsed signal as selected. The pressing force of the internal press roller 47 can therefore be controlled by adjusting the directive pulsed signal.
the external peripheral surface of the stencil drum 16 is moved together with the external peripheral surface of the opposite 17 located close thereto in the same direction during the rotation thereof, while the stencil sheet wound on the stencil drum 16 is pressed against the paper 22 passing between the stencil drum 16 and the opposite 17 by driving the printing press motor 48 in accordance with the directive pulsed signal as selected, so that an image formed on a stencil sheet is printed onto the paper 22 in accordance with the stencil printing mechanism.
the respective stencil drum and the respective machine body can be endued with dispersed characteristics due to the dispersion of the accuracy of setting the stencil drum 16 and the printing mechanism 4 and so forth.
the pressing force against the stencil drum 16' deviates from a desired value due to an error d ⁇ in the driving angle of the internal press roller 47 so that the image as printed with the stencil drum 16' is different than that as printed with the stencil drum 16 because of the differential accuracy of setting the stencil drums.
the present invention has been made in order to solve the shortcomings as described above. It is an object of the present invention to provide a stencil printing machine capable of preventing the printing quality of images from being dispersed due to the dispersion of the accuracy of setting the respective stencil drums and the like.
a stencil printing machine recited in claim 1 comprises a stencil drum and a opposite which are a pair of cylindrical parts located with their external peripheral surfaces being close to each other, a stencil sheet being detachably wound on the external peripheral surface of said stencil drum, and serving to perform stencil printing process by rotating said stencil drum and said opposite in order that the external peripheral surfaces thereof are located close to each other and moved in the same direction while said stencil sheet is pressed against said opposite, and by making said stencil sheet in contact under pressure with a sheet of paper passing between said stencil drum and said opposite by the pressing force of said stencil drum, wherein said stencil drum is detachably mounted on said stencil printing machine and provided with a storage unit for Storing information about the pressing force of said stencil drum against said opposite.
the present invention as recited in claim 1, it is possible to prevent the pressing force from varying due to dispersed characteristics of the stencil drums which are caused by the dispersion of the accuracy of setting the stencil drum and so forth.
the information about the respective pressing forces of the respective stencil drum is stored in the storage unit provided for the respective stencil drum and is used for adjusting the printing press as applied. It is therefore possible to prevent printed images from being lightened or darkened.
a stencil printing machine recited in claim 2 comprises a stencil drum and a opposite which are a pair of cylindrical parts located with their external peripheral surfaces being close to each other, a stencil sheet being detachably wound on the external peripheral surface of said stencil drum, and serving to perform stencil printing process by rotating said stencil drum and said opposite in order that the external peripheral surfaces thereof are located close to each other and moved in the same direction while said stencil sheet is pressed against said opposite, and by making said stencil sheet in contact under pressure with a sheet of paper passing between said stencil drum and said opposite by the pressing force of said stencil drum, wherein said stencil drum is detachably mounted on said stencil printing machine and wherein a machine body of said stencil printing machine is provided with a storage unit for storing information about the pressing force of said opposite against said stencil drum.
a stencil printing machine recited of claim 2 further comprises a standard pressing force determination unit for determining a standard pressing force; a correction value calculation unit for calculating a correction value by the use of the information about the pressing force as stored in said stencil drum and the information about the pressing force as stored in said machine body; and a calculation unit for calculating the pressing force by the use of said standard pressing force and said correction value.
the correction is conducted by the use of the correction values calculated with respect to the standard pressing forces for the respective stencil printing machines and the respective stencil drums. It is therefore possible to prevent the printing press as applied from being dispersed due to the dispersion of the characteristics of the individual stencil printing machines and the individual stencil drums even when an arbitrary combination of one of the stencil printing machines and one of the stencil drums is used.

the internal press roller 47 is located inside of the screen 19 of the stencil drum 16 as part of an internal press mechanism 20.
a paper clamp 21 is provided at a predetermined location of the external peripheral surface of the opposite 17 for clamping the leading edge of a printing sheet 22.
the paper feed mechanism 5 is composed of a paper feed tray 23 in which a number of the printing sheet 22 are stacked as a printing medium, a scraper 24 for coming into abrasive contact with the uppermost sheet of the printing sheets 22 on the paper feed tray 23, a picking up roller 25 and a separating roller 26 which are located close to each other in the downstream side of the scraper 24, and a guide roller 27 and a timing roller 28 which are located close to each other in the downstream side of the picking up roller 25 and the separating roller 26.
the printing sheet 22 is transported to the picking up roller 25 and the separating roller 26 by the rotation of the scraper 24. Any lower sheet other than the uppermost sheet 22 is not allowed to be transported by means of the picking up roller 25 and the separating roller 26.

the printing mechanism 4 serves to clamp the leading edge of the stencil sheet 15 as prepared by the stencil making mechanism 3 by means of the stencil clamp 18 of the stencil drum 16, which, in turn, rotates with the stencil sheet 15 being clamped in order to mount the stencil sheet 15 by winding the stencil sheet 15 on the screen 19 forming the external peripheral wall of the stencil drum 16
the paper feed mechanism 5 serves to transport the printing sheet 22 in synchronism with the rotation of the stencil drum 16 and the opposite 17 by means of the paper clamp 21 of the opposite 17 through between the stencil drum 16 and the opposite 17.
the internal press roller 47 is located in the stand-by position apart from the screen 19 in the printing mechanism 4 when the actual printing operation is not performed.
the internal press roller 47 is pressed against the stencil drum 16 while the stencil drum 16 is rotated.
the internal press roller 47 then rotates on the internal peripheral surface of the screen 19 while the internal peripheral surface of the screen 19 is outwardly pressed by the internal press roller 47 aside of the peripheral position of the stencil clamp 18. Since the external peripheral surface of the internal press roller 47 is continuously supplied with ink 53, this rotation causes the ink 53 to be transferred to the screen 19.
the screen 19 is expanded in the radial direction under the pressing force of the internal press roller 47 so that the screen 19 is in contact with and pressed against the opposite 17.
the printing sheet 22 is passed through between the stencil drum 16 and the opposite 17 by means of the paper feed mechanism 5 as described above, and then pressed between the internal press roller 47 and the opposite 17 together with the screen 19 and the stencil sheet 15.
the ink 53 is transferred through the perforation of the stencil sheet 15 to transcribe the image information to the printing sheet 22.
the paper clamp 21 is released.
the paper discharging mechanism 6 serves to guide the leading edge of the printing sheet 22 by means of the upper blocking guide member 30 or to peel off the leading edge of the printing sheet 22 adhering to the opposite 17, followed by transporting the printing sheet 22 to the stacking tray 34 by means of the printing sheet transportation mechanism 33.
the stencil discharging mechanism 7 serves to discharge the previous stencil sheet 15, as a used sheet, wound on the external peripheral surface of the screen 19 of the stencil drum 16.
the leading edge of the stencil sheet 15 is released from the stencil clamp 18 of the stencil drum 16, then guided by means of the stencil discharging guiding belt 36 with the stencil drum 16 being rotated, transported to the discharged stencil box 37 by means of the pair of the stencil discharging transportation belt 36 and stored in the discharged stencil box 37.
the stencil printing machine 1 in accordance with the present embodiment is provided with a main control section 100 in the machine body for controlling the entire operation of the stencil printing machine 1 and a stencil drum control section 200 in the stencil drum 16 for controlling the operation of the stencil drum 16.

the drum A detecting sensor 211 serves to detect the position at which the drum is to stop.
Fig.6 is a block diagram schematically showing the calculation of the standard operation quantity.
the printing press is applied to the stencil drum 16 by means of the printing press motor 48 located in the machine body 1 as the pressing force of the internal press roller 47 located in the stencil drum 10.
the printing press motor 48 is controlled by the pulsed signal and generates driving power to the internal press roller 47 through the spring 49 to control the pressing force of the internal press roller 47 against the internal surface of the stencil drum 16.
the operation quantity T [pulse] of the printing press motor 48 is determined by the standard operation quantity Tr, the stencil drum printing press correction value Td and the machine body printing press correction value Tm.
the standard operation quantity Tr is determined by the printing speed and the printing density which are required by a user and the temperature of the stencil drum when printing. More specifically speaking, an appropriate operation quantity is calculated with standard to the data table stored in the storage unit 103 and the like to be the printing speed and the printing density which are input through the manipulation panel 105 by a user or which have been preset before shipping from a factory.
the correction control is conducted by adding the stencil drum printing press correction value Td and the machine body printing press correction value Tm to the standard operation quantity Tr.
the stencil drum printing press correction value Tm is obtained experimentally and heuristically as a correction value corresponding to the deviation of the operation quantity of the printing press motor 48 for generating the standard printing press from the standard operation quantity.
the stencil drum printing press correction value Tm is preset before shipping or set in the course of maintenance afterward.
a directive pulsed signal X is determined as the standard directive pulsed signal X with which the printing press motor 48 is driven to produce a printing press force of 5 kg against the opposite 17 in the case that the stencil drum 161 is mounted on the stencil printing machine 1.
the printing press motor 48 is driven to produce a printing press force of 5 kg against the opposite 17 with a directive pulsed signal (X+20) in the case that the stencil drum 162 is mounted on the stencil printing machine 1
the deviation of +20 is determined as the stencil drum printing press correction value Td of the stencil drum 162.
the printing press motor 48 is driven to produce a printing press force of 5 kg against the opposite 17 with a directive pulsed signal (X-20) in the case that the stencil drum 163 is mounted on the stencil printing machine 1, the deviation of -20 is determined as the stencil drum printing press correction value Td of the stencil drum 163.
the machine body printing press correction value Tm is a value which is to be stored in the storage unit 103 of the main control section 100 and the like and obtained for example by experiments as an average standard value which is obtained corresponding to the deviation of the operation quantity of the printing press motor 48 for generating the standard printing press from the standard operation quantity.
the stencil drum printing press correction value Tm is for example preset before shipping for each stencil printing machine.
a directive pulsed signal X is determined as the standard machine body printing press correction value Tm for the stencil printing machine 1A with which the printing press motor 48 is driven to produce a printing press force of 5 kg against the opposite in the case that the stencil drum 16 is mounted on said each stencil printing machine 1A.
the printing press motor 48 is driven to produce a printing press force of 5 kg against the opposite with a directive pulsed signal (X-10) in the case that the same stencil drum 16 is mounted on the stencil printing machine 1B, the deviation of -20 is determined as the machine body printing press correction value Tm of the stencil printing machine 1B.
the printing press motor 48 is driven to produce a printing press force of 5 kg against the opposite with a directive pulsed signal (X+10) in the case that the same stencil drum 16 is mounted on the stencil printing machine 1C, the deviation of -20 is determined as the machine body printing press correction value Tm of the stencil printing machine 1C.
Fig 10 is a flowchart showing the printing control process.
the standard operation quantity Tr is determined (S801).
the determination of the standard operation quantity Tr is conducted with standard to the data table stored in the storage unit 103 on the basis of the values as set of the printing speed and the printing density and the temperature of the stencil drum when printing as described above.
the stencil drum printing press correction value Td as stored in the storage unit 203 for the stencil drum is read out as well as the machine body printing press correction value Tm as stored in the storage unit 103.
the operation quantity of T is calculated on the basis of the respective correction values Td and Tm (S802). Namely, as described above, the operation quantity of T is calculated by adding the stencil drum printing press correction value Td and the machine body printing press correction value Tm to the standard operation quantity Tr.
a main motor is then driven (S803) while a loop for wait is repeated to detect a target speed reached of the main motor (S804). After the speed of the main motor reaches the target speed, a sheet discharge motor begins rotating (S805), and the printing press motor 48 is driven with the pulsed signal corresponding to the operation quantity of T in order to adjust the printing press as applied.
a next sheet of paper is feed (S807) to continue the printing operation while judging whether or not the remaining number of sheets of paper for the current printing task is 0 (S808).
the remaining number of the sheets to be printed is the desired number of copies as from which is subtracted the number of copies having been actually printed, and becomes 0 when the printed number reaches the desired number of copies. If the remaining number of the sheets to be printed is not 0, the paper is feed to continue the printing operation by the loop process. When the remaining number of the sheets to be printed becomes 0, null pulse signal is given to the printing press motor (S809) to stop the respective motors (S810) and terminate the printing operation.
Fig.11(a) is a flowchart showing the operation of the main control section 100.
the main control section 100 is operated to conduct initialization (S701).
the stencil drum printing press correction value Td is read out from the stencil drum 16 through the machine body/stencil drum communication units 104 and 212 while the machine body printing press correction value Tm is read out from the storage unit 103 and the like (S702,S703).
a keystroke receiving process is then conducted (S704), followed by a panel displaying process (S705) to initiate a stencil sheet making operation or the printing operation (S706).
the printing speed and the printing density required by a user can be obtained in order to determine the standard operation quantity Tr as explained heretofore in the step S801.
Fig.11(b) is a flowchart showing the operation of the stencil drum control section 200.
the main control section 200 is operated to conduct initialization (S707) and confirmation of the ink bottle (S708).
the stencil drum printing press correction value Td of the stencil drum 16 is then transferred to the machine body (S710). Namely, the stencil drum printing press correction value Td stored in the storage unit 203 is read out and transferred to the machine body/stencil drum communication unit 112 of the machine body through the machine body/stencil drum communication unit 212.
the operation quantity of the printing press motor T is calculated by the use of the stencil drum printing press correction value Td transmitted from the stencil drum 16 and the like in order to adjust the printing press on the basis of the operation quantity of the printing press motor T as calculated. Furthermore, while indication of the printing operation is transmitted from the machine body to the stencil drum 16, the stencil drum 16 serves to control the ink motor in order to supply ink to the inside of the stencil drum 16 (S711).
Fig.12 is a flowchart showing the operation of the confirmation process.
SW information 000 (S901) in the course of the step S708 as described above.
the SW information is information relating to the bottle set SW about the existence of the ink bottle as set in the stencil drum 16, the color of the ink bottle and so forth.
the SW information is not 000, it is indicated that an ink bottle is set.
the instant bottle code SW is a code indicative of the type of ink and so forth as initialized or as set by a user.
the instant bottle code when it is judged that the instant bottle code is not the SW information in the step S902, it is determined that a wrong ink bottle is set and an error is registered (S903) followed by terminating the process (S904). Namely, the error information indicative of a wrong ink bottle is registered in the machine body where a predetermined indication is displayed in the manipulation panel in accordance with the error information.
the confirmation process of the ink bottle is terminated (S904) followed by the steps subsequent to the step S709.
the printing press correction values Td and Tm as the information about the respective pressing forces of the current stencil drum and the machine body are stored in the storage unit 203 of the individual stencil drum and the storage unit 103 of the individual machine body and are used for adjusting the printing press as applied. It is therefore possible to prevent printed images from being lightened or darkened.
the standard operation quantity Tr indicative of the standard pressing force is determined for each of the respective correction values Td and Tm while the differential values therefrom are preset before shipping or set in the course of maintenance afterward, and used as correction values. It is therefore possible to prevent the printing press as applied from being dispersed due to the dispersion of the characteristics of the individual stencil printing machines and the individual stencil drums even when an arbitrary combination of one of the stencil printing machines and one of the stencil drums is used.
